When placed at a new desk the first thing you'd do was check what the graffiti was on the desk. Our school was tolerant of graffitti as long as it didn't contain swear words. One day me and my gang of friends decided to write 'Fuck Me' on our desks. Unfortunately someone else was spotted writing 'Graham is a prick' or something on their desk at the time. The teacher came over and went berserk. He said he was then going to walk down each aisle to check if anyone else had swore on their desk. Quickly we decided to try and amend what we'd written. I came up with 'Fookey Meou', others came up with other stupid variations. Unfortunately one of us missed the point of the exercise entirely, and amended his to 'Fuck me mother'. Our enormous laughter at this foolishness brought the teacher over right away. We all got the ruler.
